To all lwhom tmag concern: 4

Beit known 'that-l, `W'ILLIAM E. MODON- nLL, a citizen of the United States, and resident of Rochester, in they countyoffMonroe e and State ofNew York, have invented certain new and useful llmprovementsfin Ophthalmic .Mountingml 0f which the i fol'- lowing is a specification,4 y

The present invention `relates to ophthal- 10 mic mountin sand more particularly tothe type made om-zylonite `or-simi1arnonmetallic material. object of this invention 'is to provide :an improvedvmanner of connecting thetern les to the'ltrame'which 15 carries the lenses, .t 's connecting Ineansbe.`

" ing electivelysecuredv to each temple. and

the `frame and being inconspicuous when viewed from thefront of the mounting. 1 A

further objecty of the invention-iste provide `at a construction in which the hinges between the temples and the frame lmay be `tightened to prevent loose play. ofthe temples on the frame 'carryingthe lenses. Still-another object of the invention is to provide an im 25 proved hin e member which may beedec-l tively embe ded in a non-metallic lens" frame or temple so Aas nottorbecomc-readily deisconnectedfrom such rpart. l y

@To these and other ends, the invention f t@ consists of certain parts and-combinations of parts, fall-of` whlch" will be hereinafter described: 'the novel "features being y pointed outinthe appended'cla'ims...y` p f y 2 `lln thedrawings:4 f

ber t at connects with the'temp'le; and y Figs. 10 andv 11 are, respectively, lan tt and side views of the washer interpose tweenv thefears of the temple hinge member.; f In the illustrated embodiment of V.the drawings, there-is emplo ed a frame formed of non-metallicmateria such as zylonitc, and provided with two lens :rings 11 con t@ nectedby a bridging portion.` 2, cach ring 1y preferably having atA its outer edgea pro jection r or extension 3 to which the temples 4 are pivotally connected, the-tem lesbeing provided at `their ends ...with evelled 05 portions 5 whichl cooperate with.'` bevelled portions 6 on the extension y3 `to kliinit th outward swinging'ot the temples.l i

i The hinge connection, in thls* embodiment employs two members, oneemb'cddedin the 7(l trame-andv the other 'ini` theetemple. 1 The oneembedded" in the frame embodies a llshaped piece'providing two arms 7 connected by a resilient bend .8.v On one side 'ot the -saidU shapedf ortion three 4anchoring lngs .75

9 may be providedf." .These lugs, in4 this 1nstance, `have enlarged ends and are arranged, one at the bend 8 and the other two at the outer lends. of the armsV 7 On the other sides A Y of the arms 7, ears. 10 and 11 are provided, 5f one of' these ears Abeing longer thanfthe other, so that the `pivot pin 12 which connects theears may lie with its-j axis at an angle to the plane of. the frame inv ordery that the frame may lie ina vertical position on the @t Yface.` The pivotpin 1 2 has a head 13 engaging the outerface'of `the lug 11 Aand a screw threaded portion 14 en aging in the vlug `or ear 10; ln attachingiehingemember to the lens frame, the hinge member is heated to and, while in a heated condition, `is'forced into the rear face of the zylonite or nonmetallic extension 3 soy that the ends of Vthe arms 7 lie inimmediatefproximaty to the bevel 6, the U-shaped portion 8 being also 95 embedded within .the material so that l.its

.upperface is ush with the rear -face ot ating between theears 10 and 11.

` a binding action' on the hinge member opere 'The hinge member secured to each templei Wi 'f 4 is also in the form ot twb arms indicated j Fi 9 is an end view of thehinge "emat" 15 and connectedby a bend 16. 'llhe U- oring v projections .17 with enlarged heads, one projection o at the bend and Mt the'other two `being yat the free ends ofthe portion withthe headed ,anchoring pro]ec-,

vided with perforated ears 18. The U-shaped tionsf17 is embedded in the temple, asshow'n in Fig. 4:, sfthat theends of the arms 15 will be positioned substantially at the inner edge thalmic.mounting in which ,the `temples are a will be'seen that Fromy the foregoin' ged an improved ophthere 'has beenr provi connected; to the Y lens'l .frame extensions through hinge `members which are embedded vinthetemplesand-the lens frame extension.

.These hinge; members embody Uhshapedl por- .tions embedded .inthe parts' to wluch they are attached and having ears on the ends of their arms through which ythe pivot pins extend. 1 The U-.shapedportions also each have headed 'anchoring projections lextending `:from the; connecting ,portion "between the `1 arms vandalso `:from the arms near the ends thereof:y V'There has also been provided a hingeconstruction in which therpivot ears Y are mounted. ony arms, resiliently connected together, thus permittingthe lears to be moved ytoward-Teach A'other' under the action of th'eolpivotscrew to produce a binding action on the hinge member betweeny such ears.

It will be noted thatthe U-shaped member has itsfears/'nearer one end thereof than the other and that the anchoring projections are yarran ed at opposite ends of thismember,

f .one o ,the Llrojection's being-nearer the ears than-*the-ot er. `Bythis'arrangement the strain 'onthe anchoring projections is so dis-l tributedzthat ,theflpossibility of the hinge memberjbein disconnected Afrom the nonmetallic part `1s reduced `to a minimum. v

- Whatl claimas m invention and desire to secure by Lettersl atent is:

` In combination with a part made from non-'metallic material, afhinge member havy ing twolears, and a U-shaped .portion from vthesides ofthe arms of ,which said ears ex-V tend parallel with. saidarms, said U-shaped i 'i 4portion beingembedded inthe non-metallic material. v

= f2. In.,'coi nbination with .a part 'made of non-metallic material, a U-shaped portion embedded in said material land having. anchori projections'extending `from the arms there' vrand alsoA fromgthe connecting portionlbetween the arms and pivot rears extend-A ing A`from the oppositesides of said arms.

` l ',3. Inlcombinationvwith two parts, atleast one oi which is madeof non-metallicmaterial, a hinge connection between the parts embodying a hinge member connected vto a part made.v of non-metallic. material, said binding action on the hinge member embed ing two arms resilientlyg connected to et er and embedded in the material and :iso embed ing two ears extendin from said arms, a inge member on the ot er part received by the said ears, and a pivot' pin connecting said ears to produce a binding action on the hinge member between the ears.A

z 4. -In combination with two parts, at least one of which is made of non-metallic material, a hinge connectlon between the members embodying amember having two ears and a resilient connection kbetween the ears, said hinge connection also embodying a member on the 'other part received between the ears, and a pin connecting1 the ears to produce inge member received betweenthe ears.

5. rIhecombination with a lensframe of nonvmetallicmaterial provided with extensionsat opposite sides, each of said extensions'having a., bevelled end portion and temples of non-,metallic material having bevelled ends for cooperation with the bevelled ends of thevextensions, of hinges connecting the temples to the lens frame, each hin e embodyingl two members, each member, aving a U- aped portion embedded in the 4non-metallic material of the part by which it is carried, so that the face thereof is iiush with such part,- the free ends of the arms ofk said U-shapedportion being adjacent the bevelled portion of the ears carried by said arms near t eir free ends and ivotally connected to the ears on' the other in e member.

6. The com ination with two partsmade of non-metallic material and each 'having art, and

cooperating bevelled portio'ns, a hinge con- 'necting said parts `embodying two hinge members, each formed with two connectin arms embedded inthe non-metallic materia and ears extending from said armsand ivotally connected to the earsv on the ot er hinge member. v

7. The combination,l inv an ophthalmic mounting, of anon-metallic lens frame hav ing a projection extending outwardly 'therefrom, and a temple, of a .hingeconnection between the temple, and `the projection embod ing a member-embedded 1n the rear ace of t e projection and having anchoring projections extending into said lens frame and ormedwith shoulders, the face of the mem-y ber bein substantially flush with the rear face of t ev extension on the lens frameand the member having earsk extendingbeyond said face to which the temple is hin ed.

8. The combination, in an op thalmic mounting, of a non-metallic lens frame havinga projection formedwith a bevelled end, and a temple having its inner end formed of non-metallic material and bevelled, of a hinge connection between the temple and the :frame projection, embodying two memmimic bers one secured to the temple and the other to the frame projection and each having a body portion embedded in the part of the mounting to which it is secured, the face of each member being fiush with the face of the art in which it is embedded and each memer having ears extending from such face and pivoted to the ears `of the other member,

lit-"Nul ple having an vinner end formed of nonmetallic material and bevelled to cooperate with the bevelled portion on the rejection, of a hinge connection between e temple and the projection of the lens frame embodying two members, one secured on the inner side of the temple andthe other secured on the rear face of the projection, each of said members having two ears projecting therefrom and pivotally connected to the ears of the other member and each of said members extending to one side of the ears and having an anchoring projection adjacent thee'ears, and an anchoring projection on that end farthest. removed from the ears. f
